AXLE TORQUE GRADE ASSIST
DRIVE
August 14, 2025
A vehicle includes a system that performs a method of operating the vehicle. The system includes a road grade sensor for measuring a road grade of a road section being traversed by the vehicle, a speedometer for measuring a vehicle speed, a power flow direction sensor for obtaining a power flow direction of the vehicle, a pedal position sensor for measuring a pedal position, and a processor. The processor is configured to determine an axle torque upper limit for a motor of the vehicle based on the road grade, the vehicle speed and the power flow direction, determine an axle torque request based on the vehicle speed and the pedal position, determine a clipped axle torque request from the axle torque request and the axle torque upper limit, and control the vehicle by implementing the clipped axle torque request at the vehicle.
